Bug description:
  Description:	Ubuntu 22.04.4 LTS
  Release:	22.04

  Running do-release-upgrade

  Could not calculate the upgrade

  An unresolvable problem occurred while calculating the upgrade.

  This was likely caused by: 
  * Unofficial software packages not provided by Ubuntu 
  Please use the tool 'ppa-purge' from the ppa-purge 
  package to remove software from a Launchpad PPA and 
  try the upgrade again. 

  If none of this applies, then please report this bug using the 
  command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal. If 
  you want to investigate this yourself the log files in 
  '/var/log/dist-upgrade' will contain details about the upgrade. 
  Specifically, look at 'main.log' and 'apt.log'. 

  
  Restoring original system state

  
  I've tried all of the normal cleaning of source repos and disabling third-party repos.  Nothing really helps.  It looks like core pieces of Xubuntu are causing the problem from the logs and that shouldn't be the case.

  Last few lines of /var/log/dist-upgrade/main.log are as follows:
